KWS-V2000 Indicator Operation Manual
Thank you for purchasing the KWS-V2000 indicator. Please read all operating instructions carefully
before use and keep the following points in mind:
* Avoid lengthy exposure to extreme heat or cold, your scale works best when operated at normal room
temperature. Always allow the scale to acclimate to a normal room temperature before use
* Allow sufficient warm up time. Turn the scale on and wait for a few minutes if possible, to give the internal
components a chance to stabilize before weighing.
* These electronic scales are precision instruments. Do not operate near an in-use cell phone, radio, computer
or other electronic device. These devices emit RF and can cause unstable scale readings. If your scale ever
performs poorly, try moving the scale to a different room or location.
* Avoid using in condition of heavy vibration and airflow.
* Read the weight reading in short time after loading. The output signature of load cell and electronic circuit
may be little influenced after weighing for a long time.

8. HOLD Function
8.1 HOLD function can be used to freeze display number. In this mode, scale can catch a dynamic number,
hold a stable number, or average a unstable number, then HOLD(freeze) this number temporary for user
to watch or record. This function can be used in normal weighing mode, counting mode and percent
weighing mode. After entering HOLD mode, the speed of A/D converter can be increased to 80Hz (if

USER-HOLD-AD.H.SPD is set to YES) from original 10Hz for some dynamic weighing applications. With
the hold function, it is possible to weigh restless weighing samples such as live animals, moving objects.
The indicator provides special mode settings to accommodate sample’s movements.
8.2 To make HOLD function be active, the CONFIG-FUNC-HOLD menu item must be set to YES; menu items
of USER-HOLD-HLD.MOD /-AVG.TIM /-HLD.TIM /-DYN.RNG /-STB.TIM, USER-OTHER-NLD.RNG
need be set to reasonable value.
To speedup sampling of weight, set USER-HOLD-AD.H.SPD menu item to YES.
To enter HOLD working mode, press down HOLD key when scale works in normal weighing mode,
counting mode or percent weighing mode.
8.3 There’re several HOLD mode to freeze display data:
(1) Positive Peak Number HOLD mode
(2) Negative Peak Number HOLD mode
(3) Toggle HOLD mode
(4) Average HOLD mode
(5) Auto HOLD mode
The following are details of these HOLD modes:
8.3.1 Positive Peak HOLD:
When USER-HOLD-HLD.MOD is set to PS.PEAK, the hold mode is positive peak hold mode. When
scale first enters this working mode, it will display the largest positive number that is from the time of
zero-pint set. After entering this working mode, scale will always catches and refresh positive larger
number and display it. To exit HOLD mode, press HOLD key again.
8.3.2 Negative Peak HOLD:
When USER-HOLD-HLD.MOD is set to NG.PEAK, the hold mode is negative peak hold mode. When
scale first enters this working mode, it will display the largest negative number that is from the time of
zero-point set. After entering this working mode, scale will always catches negative larger number and
display it. To exit HOLD mode, press HOLD key again.
8.3.3 Toggle HOLD:
When USER-HOLD-HLD.MOD is set to TOGGLE, the hold mode is toggle hold mode ---a manual Hold
function. After entering this working mode, scale will freeze and display number if scale is stable. Only
the weight that is over USER-OTHER-NLD.RNG (zero 'dead' band ) can be held. To exit HOLD mode,
press HOLD key again. If the time of scale being unstable is more than USER-HOLD-STB.TIM, STB.ER
will be shown, press TARE key to start averaging again, or press HOLD key to exit.
8.3.4 Average HOLD:
When USER-HOLD-HLD.MOD is set to AVERAG, the hold mode is average hold mode. After entering
this working mode, scale will freeze and display number if scale is stable. If scale is not stable, but the
variation is less than USER-HOLD-DYN.RNG, scale will average data in USER-HOLD-AVG.TIM, then
freeze and display the number. Only the weight that is over USER-OTHER-NLD.RNG can be frozen.
Scale will exit HOLD mode according to the setting of USER-HOLD-HLD.TIM. If the time of scale
variation being over USER-OTHER-NLD.RNG is more than USER-HOLD-STB.TIM, STB.ER will be
shown, press TARE,UNIT,ACC or PRINT to start averaging again, or press HOLD key to exit.

8.3.5 Auto HOLD:
When USER-HOLD-HLD.MOD is set to AUTO, the hold mode is auto hold mode--- different subjects
can be weighed one after another without pressing any buttons. After entering this working mode, scale
will freeze and display number if scale is stable. If scale is not stable, but the variation is less than
USER-HOLD-DYN.RNG, scale will average data in USER-HOLD-AVG.TIM, then freeze and display the
number. Only the weight that is over USER-OTHER-NLD.RNG can be frozen. If the held weight is
moved away, and a new load put on the scale, scale will automatically hold new number of load. Scale
will exit HOLD mode according to the setting of USER-HOLD-HLD.TIM. If the time of scale variation
being over USER-OTHER-NLD.RNG is more than USER-HOLD-STB.TIM, STB.ER will be shown,
press TARE to start averaging again, or press HOLD key to exit.
8.4 In Positive or Negative Peak HOLD mode, the red HOLD (for LED version) or PEAK and HOLD (for LCD
version) announciator will be lighted, in other HOLD mode, green HOLD (for LED version) or HOLD (for
LCD version) announciator will be lighted. When HOLD announciator flash, the displayed number is live,
When HOLD announciator become steady, the displayed number is frozen.
9. Data Compare Function
9.1 Data compare function can be used in normal weighing mode, counting mode and percent weighing mode,
and call it as Check Weigher, Check Counts and Check Percentage. When this function is enabled, you
can set a higher and a lower limitation of weight , counts or percentage independently, and these
limitation can be saved permanently. Then, the current data of weight , counts or percentage will be
compared with the setting limitation, and corresponding announciator will be lighted.
9.2 To make data compare function be available, CONFIG-FUNC-COMPAR menu item should set to YES,
and high and low limitation should be set correctly according to following steps:
9.3 In in normal weighing mode, counting mode or percent weighing mode, Press down DATA key more than
3s to enter input compare data of high and low mode.
9.4 After HIGH being shown, last setting data of high will be displayed, use PRINT, ACC, UNIT key to input
new number of high and press TARE key to confirm. Announciator of Hi will be shown in this step. Press
ZERO key to exit and back to original working mode.
9.5 After Low being shown, last setting of low will be displayed, use PRINT, ACC, UNIT key to input new
number of low and press TARE key to confirm. Announciator of Lo will be shown in this step. Press ZERO
key to exit and back to original working mode.
NOTE:
If High number is 0 or is equal or less than low number, the comparison will be disabled.
9.6 After a reasonable limitation is set and compare function is be active, one of announciators HI, OK, LO will
be lighted, and the beeper will sound according to its setting in USER-BEEP.

10.1 Accumulation function can be used in normal weighing mode, counting mode and percent weighing
mode, When this function is enabled, you can accumulate current net weight, piece, and percentage.
Note, only the load on scale is larger than USER-OTHER-NLD.RNG, the displayed positive number can
be added up. The accumulation times and total can be displayed or printed.
10.2 To make data accumulation function be available, CONFIG-FUNC-ACCUMU menu item should set to
MANUAL or AUTO, Following are details.
10.3 When CONFIG-FUNC-ACCUMU is set to MANUAL, the stable and positive displayed net weight (must
be larger than USER-OTHER-NLD.RNG), piece or percentage can be accumulated by long pressing
TOTAL key, and indicator will display accumulation times first, and then display total of number. To avoid
repeating accumulation for same load, one load only can be accumulated once. So, before a new load put
onto the scale, the original load should be removed and let load on scale be smaller than
USER-OTHER-NLD.RNG.
10.4 When CONFIG-FUNC-ACCUMU is set to AUTO, the stable and positive displayed net weight (must be
larger than USER-OTHER-NLD.RNG), piece or percentage can be accumulated automatically, and
indicator will display accumulation times first, and then display total of number. To avoid repeating
accumulation for same load, one load only can be accumulated once. So, before a new load put onto the
scale,
